State Agencies Warn of Possible Future Power Shortages

By Greg Halbleib Dec 22, 2025 | 5:03 AM

Illinois’ electric grids may soon face power shortages and further price increases as fossil fuel plants go offline and data centers fueling the rise of artificial intelligence demand ever-increasing amounts of power.

Capitol News Illinois reports that’s the conclusion of a new report by three state agencies that foreshadows an upcoming state grid planning process and a potential legislative fight on how lawmakers will regulate power-hungry data centers, if at all.

The projected shortfalls would begin in the Commonwealth Edison service territory in northern Illinois by 2029 and in the Ameren service area that covers most of downstate Illinois by 2031.

They’d continue to worsen and make Illinois more reliant on energy imports without action by state policymakers or grid operators.
